wardly slanting member 11, insures a very rigid bracing of the rearwardly extending bar 6 and also of the rearwardly slanting bars 7 and 11.

In the form of the invention shown in Figure 3, substantially the same inventive idea is followed. In this form of the in vention, the main bar 14 is adapted for attachment to the finger bar by means of the clips 15, as previously described.

The bar 14 carries the rigidly attached slats 16 and alsocarries rigidly attached bars 17 18 and 19, which extend directly rearwardly. These last three bars are provided with rearwardly slanting end bars 20, 21 and 22, which are integrally formed with the rearwardly extending, rigidly attached bars.

The same method of strengthening. or bracing, the rearwardly extending bar 19 is employed as that previously described. A slanting bar 23'is rigidly attached to the bars 14 and 19 and is integral with the rearwardly extending portion 24, and with the rearwardly andslanting projection portion 25. The bars 20, 21, 22 and 25 are all rearwardly These bars carry the swinging slats 26, 27, 28 and 29 respectively.

All of the slats are provided with upturned. rear ends in both forms of the invention, and are of diiierent lengths so as to secure the proper feeding and discharge of the mowed material, as the slats are dragged over the ground behind the mower.

Further, the rearwardly slanting portions, which carry the innermost of the swinging slats, are located behind the innermost wheel of the mower, and thus insure the catching of all of the mowed material.

Further, it is to be noted that the bars 10 and 24, as shown in Figures 1 and 3, are attached to the rearwardly extending bar in each case at spaced points, and thus a very rigid bracing or strengthening effect is produced.

In the last described form of the invention shown in Figure 3, the same facility in turning is afforded as in the first described form. The swinging, pivotally mounted slats readily permit the free turning of the mower at the end of each swath, and also insure the bunching of the material without wasting or without scattering such material. 7 It will be seen further that. the wmdrower is so constructed that the minimum 7 amount of strain is imposed thereon,although Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting, as the invention may be variously embodied and as the scope of such'invention is to be determined as claimed.

I claim:

1. A windrower attachment for a mowing 'machine' having a finger bar, said attachment machine having a finger bar, said attach ment having a main bar, means for attaching said main bar to the finger bar of the mowing machine, a rearwardly extending bar rigidly attached adjacent the innermost end of the main bar and having a rearwardly slanting portion, a plurality of swinging slats pivoted to said rearwardly slanting portion, a plurality of rearwardly extending slats rigidly attached to said main bar, a diagonal bracing bar secured to said main bar and having a portion secured to said rearwardly extending bar and terminating in a rearwardly and outwardly slanting portion, and a slat hinged tothe end of the last mentioned portion.

3. A windrower attachment for 'mowing machines having a finger bar and a main'bar secured thereto, a rearwardly extending bar rigidly attached adjacent the inner end of the main bar and having an obliquely disposed portion extending rearwardly and back of the mower wheel, a plurality of slats'pivoted to the obliquely disposed portion, a plurality of rearwardly extended slats rigidly attached to the main bar, and auxiliary bars rigidly attached to the main bar, each having pairs of slats in pivotal union therewith, the auxiliary bars'being positioned at the innermost end of the rearwardly extending bar.

In testimony that-I claim the foregoing I have hereunto set my hand at Manitowoc, in the county of Manitowoc and State of Wisconsin. j I V ALBERT IVETTENKAMP.
